That sounds like a plan. I wouldn't like to use a timing belt for the Z-axis (not without a torquey motor!).

I tried timing belts for my prototype, but I didn't have the steppers driven correctly so I abandoned that approach because it was too jerky. I know what I did wrong, so there's nothing wrong with that approach.

Best of luck!

if you are using two leadscrews for the Y I'd consider driving them with one motor driving through two pulleys, rather than two motors. I know of some who have made two motors work, but IMHO its a lot easier to ensure the leadscrews are driven equally by a mechanical coupling.
